Barcelona hold Dortmund to a goalless draw in Champions League opener
Borussia Dortmund vs Barcelona: as it happened!
That's the last action of the game. Barcelona held 0-0 in their first Champions League game of the season. Dortmund gave as good as they got and had a chance to win it through a penalty but Reus' shot was saved by Ter Stegen. Draw probably a fair result in the end between two attacking sides.
Ball into the back post and Messi has a chance to win it! He takes it down, has a second to think, and drives it at a defender. Lots of bodies in front of him in fairness. Never easy. Blocked.

PENALTY! Sancho goes down. He really bought that one and Semedo lunged in. Well done by Sancho. Semedo booked for his trouble.
Dortmund have started this half much better than Barcelona.
Guerreiro to take. It's perfect but Hummels is offside and he missed anyway. Really well done by Pique as he stepped out at the right time.
Arthur tosses Hummels to the ground. Free for Dortmund in another dangerous position but this one isn't as close or central.

Sancho been stymied so far.
Griezmann and Suarez link well and Witsel is forced to get back, get his body in front of Griezmann and concede the corner. Another one from the same corner that Pique had that chance earlier.

We are underway at the Westfalenstadion.
There's that music again!
We also have live coverage of Napoli vs Liverpool and Will is taking you through that one, which should be a corker!
Marco Reus starts for Dortmund. He wanted Messi to start as he wants to be challenged by the best.
As we said, Messi starts on the bench. He could be good for half an hour after completing a couple of training sessions in a row this week. Let's see if they need him.
Ansu Fati has been stealing all the headlines but Jadon Sancho is just sitting, waiting for his chance to burn someone. He's 19, which seems ancient compared to Fati's age, but Barcelona will have their hands filled with him.
Ernesto Valverde has been criticised for being to conservative at time but he opts for an attacking midfield with Arthur, Busquets and De Jong.
This very much looks like a typo but it's not. 18 games. Suárez has a chance to break that hoodoo tonight.
Alcacer gets a start against his former club. Meanwhile, there's a strong Real Madrid connection in the Dortmund side. Eden Hazard's brother starts and so down on-loan defender, Achraf Hakimi.
Borussia Dortmund XI: Burki, Hakimi, Hummels, Akanji, Guerreiro, Delaney, Witsel, Reus, Hazard, Sancho, Alcacer.
Valverde is a huge fan of Fati and has openly spoken about how special he is. He has backed him tonight again.
Peter Ofori-Quaye was the youngest player to ever score in the Champions League when he scored for Olympiakos against Rosenborg during a 5-1 win for the Norweigan side back in 1997.
Ansu Fati's incredible rise continues as he starts in the Champions League for the first time! 16, remember, he's 16.
Barcelona XI: Ter Stegen, Semedo, Piqué, Lenglet, Alba, Busquets, Arthur, De Jong, Suárez, Griezmann, Ansu Fati.
Dortmund have won three and lost one of their games so far this season. They have scored 12 in the three victories and most recently a 4-0 win over Bayer Leverkusen.
Alcacer can't stop scoring! He has seven goals in six appearances this season. And he also scored three in two with Spain on international duty.
Meanwhile, Paco Alcacer might be out for revenge tonight after his stint at Barcelona ended on a sour note. "I was treated very badly by some people at Barcelona," he said in the build-up to the game.
Ansu Fati is the talk of the town after his incredible performance at the weekend! Barcelona have offered him a big new contract too after a blistering start to his campaign and professional career.
The big news is, of course, that Lionel Messi is back after a calf injury. He hasn't played yet this season but has trained for consecutive day and could start on the bench tonight.
